it has been found objectionable for the-sash y toibe automaticallyrendered free to swing 1n-` wardly when. a predetermined slide fposition is f reached,` as this sometimes occurs Awhen pivotal sashmovement is neither expected*H nor-desired. Y .n

and 5 adjacent their inner margins grooves 10 and 41 are formedthroughout'their length f to receive outwardly and rearwardly extendning projections 11 and 42 on the plates 6 and 7 respectively, so thatthe cooperating portions 10 and 11, and 41 and 42, function as weather-Y stripng when the sashes are vertically disf pose f Intermediately oftheir length and width the sash plates 6 and 7 each have, on their innersides, a pair of parallel and longitudinal ribs 12 and 13, and 43 and44, respectively. Y The front ribs 12 and 43 extend inwardly furtherthan the rear ribs 13 and 44. Longitudinally of these sash platesadjacent their inner sides stepped projections 14 and 45 are also formedto receive the front vertical corners of the sashes 8 and 9, the sidesof which also rest against the front ribs 12 and 43. Between each pairof ribs 12 and 13, or 43 and 44m a. longitudinal slot 15, or 46, isformed in which an outwardly projecting tongue 16, or 47, integral witha sliding member 17, or 48, is arranged.v

V`The members 17 and 48 lie substantially parallel with the sides of thesashes 8 and 9 respectively, and are of such thickness that they maymove freely between the latter and theinner ribs 13 and 44. 18 and 49indicate vscrews extending through the sashplates 6 `I will now describein detail the mounting of the lower sash plates 7 on their slides 5,reference being had to Figures 7 and 11 of the drawings.

Extending outwardly from the sash plates 7 adjacent their lowerextremities are hinge pins 19 having annular flanges 20 around them ashort distance from their outer ends;

n these flanges are also spaced from their sash ner side of eachk flange20 bears against the Vsash cords-not shown.

outer side of the central portion of one of the slides 5 kand the outerends of the hinge pins-19` extend into the apertures 23 in the flexiblemembers 22. In order to remove the sash 9 all that need be done is topress the flexible'member 22 outwardly so that the pins 19 becomedisengaged from the apertures 23 the sash may then be moved downwardly'relative to the slide 5 and the pins 19 then move out of engagementfrom the slots 20.

Within the channel-shaped portion of the slides hooks 24-as shown inFigure ll-are provided to receive one end of conventional Through theslides 4 and 5 intermediately of their length slots 26 and 57 are formedthrough which locking pins 27 and 58 project. The method of supportingthese pins is identical in both sashes and is clearly shown in Figures11, 12 and 13. It consists in the provision of resilient menibers 28 and59 secured within the slides, and the said members at their free endsencircle the said locking pins. In the rear margins of the sash plates 6and 7 recesses 29 and 60 are formed which are so positioned that whenthe sash plates are vertically disposed their bases force the pins 27and 58 rearwardlyagainst the tension of the resilient members 28 and 59,but when the sash plates 6 and 7 are moved forwardly at an angle totheir slides 4 and 5 the pins are also moved forwardly by the resilientmembers 28 and 59 which` support them. On the opposed faces of the stilegrooves 2 and 3 opposed catches 32 and 61 are secured which have slots31 and 62 respectively therein. These slots are adapted to receive the`pins 27 and 58 and hold the slides 4 and 5 against vertical movement;that is, of course, provided the sashes and sash plates are movedpivotally when the slides are at such heights that the pins will engagetheir respective slots.

Extending inwardly from the opposed faces of the stile grooves 2 arestops 30 with which the lower extremities of the slides 4 come intocontact when in their bottoni position. kThe catches 32 are usually sopositioned that the pins 27 will engage the slots 31 when the slides 4rest against the stops 30.

Pivotally mounted on the inner sides of the slides 4 intermediately oftheir length are arms 33 having the sliding members 17 pivotallyattached to'their opposite extremities. These arms are so placed thatwhen the sash plates 6 are in their normal vertical positions the saidarms lie in the cut away intermediate portions 106 of the sash plates 6.As the sash 8 and sash plates 6 swing inwardly the tongues 16 of themembers 17 travel downwardly in the sash plate slots 15 until the arms33y strike the rearwardly projecting shoulders 106a formed at the lowerends of the cut away portions 106. thereby preventing further pivotalmovement of the sash plates 6.

This movement ob,`

viously draws the locking member 105 inwardly relative to the block101'andsash plate 7 .v

The locking member 105 normally extends across the path of travel of thesliding member 48 and projects through an aperture 118 in the slide 5thus holding the latter and the sash plate 7 against independentmovement. When the handle 109 is raised and thevarm 112 moved rearwardlythe locking member is moved inwardly suliiciently for the slider 5 to bereleased and also 'for the recess 100 in the said locking member to comeinto alignment with the sliding member 48 so that a portion of thelatter may pass therethrough. The upper and lower margins 48a and'48b ofthe member 48 rest adj aceiit the lower and upper sides respectively otthe locking member 105 when the sasli is in Ventilating and closedpositions respectively. n Therefore when the sash is in ventilatingposition the locking member prevents the sash from moving towards itsclosed position and the projection 7 4 which limits themovenient of theextension 71 in a downward direction `prevents the sash from swingingfurther downwardly, thus the sash is held substantially immovable inVentilating position in part by the locking device now described.Accidental releasing of the sliding members 48 can only occur when thehandle 109 is accidentally raised, since the spring 103 always returnsthe locking member 105 into such position` that its recess 96 is out ofalignment with the sliding memberl 48 and into engagement witl the slideaperture 118. While in the :foregoing the preferred embodiments of theinvention have been de`` scribed and shown, it is understood that theconstruction is subject to such further alterations and modifications asfall within the scope of the appended claims.
